Pegmatites are the traditional source of feldspar and dozens of aplito-pegmatitic fields are mined all over the World (Černý and Ercit, 2005; Dill, 2015). The major districts are in:-India, Rajasthan (Joshi et al., 2014) and Andhra Pradesh (Sarkar, 2001).-Thailand, in the Ratchaburi, Ranong and Tak provinces (Suwimonprecha et al., 1993).-

The silica-rich magmas that crystallize to form granites all contain several percent dissolved water. When the rocks crystallize, most of the minerals that form (e.g., quartz—SiO2; potassium feldspar— KAlSi3O8; and plagioclase feldspar—CaAl2Si2O8 to NaAlSi3O8) do not contain any water.
